Question

what is a disadvantage of using a space - filling model to show a chemical compound?
o space - filling models provide a two - dimensional view of the molecule.
o space - filling models do not identify the number and type of bonds.
o space - filling models do not show all atoms in the molecule.
o space - filling models show information about composition but not structure.

Explanation:

Space - filling models represent atoms as spheres and show the relative sizes and positions of atoms in a molecule. However, they do not clearly show the number and type of chemical bonds (single, double, triple etc.) between atoms. They are three - dimensional and show all atoms in a molecule and give information about both composition and structure to some extent.

Answer:

Space - filling models do not identify the number and type of bonds.
